Where I was going with the tire size question is: I think you are taxing your power steering, ecspecially when stopped. H2s have an oil cooler. All auto trans GM vehicles have at least a cooling loop thru the radiator. I'm an H3 guy, but I think you do not have a PS cooler or Trans cooler. H2 guys?????

Trans cooler kits are readily available, size based upon vehicle weight,and not too difficult to install. The same kind of cooler kit (but obviuosly a much smaller) could be used for a PS cooler.

Check the fluid. I do not know how many miles are on your two, but if the fliud is not burnt, a PS cooler would be nice, but not a necessity.

 

I will have to take a close look at the radiator area of my H2 tonight afterwork. I would almost find it appaling if they did not at least have an ATF cooler. I mean my cheap *** Dodge Durango had ATF cooler and PS cooler. It will be very interesting to find out.

 

Many GM vehicles offer a Trans cooler if you get the towing/trailering package??? I am showing my age because now days, all a trailering package means is you got the hitch with trailer lights wiring plug.

So UNTIL SOME H2 GUYS STEP UP TO HELP US as to whether Twos have a trans cooler from the factory, I'm just guessing no. If I had a Two w/o a trans cooler, I'd add one in! Dem bad boys is heavy. Heck, I put one on the old 95 Jimmy and really towed nothing heavier than my 16' Crestliner Nordic (Duck/Fishin boat).

 

not sure about the PS cooler, but i know the H2 has both a radiator loop and an external cooler for the tranny. i would recommend removing the loop through the radiator, unless you live in a cool climate, and installing a larger tranny cooler. the tranny cooler is in front of the radiator, center of grill. fitting a larger tranny cooler could be a hassle because of the way the hood mount is shaped, adding something thicker would probably create damage when you open the hood. just checked the shop manual, the PS cooler is the small cooler to the right of the tranny cooler (when looking at the truck from the front) i have a new, larger tranny cooler sitting in the garage waiting to be installed, just need to get off my *** and do it.

 

as for your question concerning being able to turn the wheels at a complete stop, there are a few things to think about. one, your tires are a good bit bigger than a passenger car, so there's a lot more surface friction on the road. what's your tire pressure? the lower it is, the more grip you'll have, unless its so low you're cupping the tires in the center. on top of all that, you've got an extremely heavy vehicle sitting on top of them. and its a good way to bend or break a tie rod if you still have stock. that's typically not a good thing unless you're trying to talk the boss into letting you buy upgraded ones.

 

Where can i get upgraded Tirods? What brand is best?

 

fabtech is the only company i know of making upgraded tie rods. there may be others by now, but my original set lasted almost 2 years before needing replaced. i've had no issues, aside from wearing out after some "gentle" offroading, and would recommend them.

 

So I actually got around to doing some work on the H2 last night. Looks like I have plent of power steering fluid. I have also notice that the only time I really have difficulty is when i have the brake pedal depressed. Also the H2 does have a Power Steering cooler. Looks to be a good size one at that.

 

Did you check your powersteering belt??

There are two serpentines.... I only looked at my main one.... the other one was pretty bad.... my problem has now disappeared....

 

I did not realize that the Engine had 2 belts but youre right. My belt going to the ps looks to be great shape. So im guessing by this pic the second belt goes to the A/C Compressor?
